angry tapir writes: "Fujitsu is breaking new ground in the cell phone market with the imminent introduction of a cell phone that splits into two parts. The F-04B was announced as part of NTT DoCoMo's new line-up and is scheduled to hit Japanese shelves in March or April next year. At first glance it looks like a conventional slider cell phone: grab onto the bottom of the phone and a numeric keypad slides out. But decouple a catch and the entire back half of the phone can be pulled off."
